Trash & Recycling

The Environmental Services Team provides curbside trash and recycling collection services to over 33,000 homes in the City, as well as a number of other collection services for our citizens. The collection service program is operated as an enterprise fund, meaning that all costs associated with providing the various services are covered by user fees.

The Trash & Recycling Collection Schedule applies to city of Thornton trash and recycle customers only.

City of Thornton trash/recycling customers are now able to download a mobile app to their cell phone or tablet! Please look for City of Thornton Recycles in the App Store and on Google Play.

Write it down!

It's a good idea to make a note of your container numbers.  Write them down or take a picture of them to keep in your phone!  If they wander away in a wind storm you'll know what cans belong to your home when you go to look for them!
